Garage Door Sensor Installation in District of Columbia
Photo-eye safety sensors are required by UL-325 on every garage door opener manufactured since 1993. They detect obstructions in the door's path and either reverse the door (during close) or refuse to start (when activated). When sensors are misaligned, dirty, sun-blinded, or failed, the door either refuses to close at all or — worse — closes without sensing an obstruction. Our sensor installation service replaces failed sensors, realigns drifted brackets, cleans the eye optics, and verifies auto-reverse on a real obstruction test.
Replacement eyes are brand-specific (LiftMaster has a different connector and signal pattern than Genie). We stock the major brands and most legacy models. Brackets occasionally need replacement when corrosion has degraded them or impact has bent them. Bracket alignment is critical — eyes that are slightly off-aim trigger intermittent close failures that drive homeowners crazy.
Every visit ends with an obstruction test: a 1.5-inch (3.8 cm) tall object placed under the door at three positions across the opening. The door must reverse when it touches the object. This is the UL-325 baseline — if the door doesn't pass, the install isn't complete. We document the test results on the work order.

Yes for matching same-brand same-generation replacements — relatively straightforward. Cross-brand replacements often don't work due to signal differences. Our flat-rate quote covers it installed, confirmed before we start.
How long does sensor work take?

What's the coverage?
1-year manufacturer coverage on replacement sensors; 10-year workmanship on the install.
Will new sensors work with my old opener?
Same-brand same-generation: yes. Different generation: sometimes, depends on the model. Different brand: rarely. We match generation when ordering.
